i have a 2001 s-10 with 4.3 that acts like it is in gear when you turn the key to start it .
after messing with it a while it starts like nothing is wrong .
would it be a sensor like a heat sensor saying its to hot or oil sensor thinking there is not enough oil or what.
make sure your park switch is adjusted correctly. the next time this happens give your gear selector a good tap into park to make sure it hit the park switch. also try starting it in nuetral when it happens and see if there is a change.
I tried puling it out of park and putting it back in. I also tried it in neutral nothing seems to work. thats why I thought it mite be a sensor of some kind. otherwise it must be the Ignition switch. And messing with the airbag is something I don't want to tackle.
